CVE-2021-26316

Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution.

CVE-2021-26402

Insufficient bounds checking in ASP (AMD Secure Processor) firmware while handling BIOS mailbox commands, may allow an attacker to write partially-controlled data out-of-bounds to SMM or SEV-ES regions which may lead to a potential loss of integrity and availability.

CVE-2021-26398

Insufficient input validation in SYS_KEY_DERIVE system call in a compromised user application or ABL may allow an attacker to corrupt ASP (AMD Secure Processor) OS memory which may lead to potential arbitrary code execution.

CVE-2020-12988

A potential denial of service (DoS) vulnerability exists in the integrated chipset that may allow a malicious attacker to hang the system when it is rebooted.

CVE-2021-26335

Improper input and range checking in the AMD Secure Processor (ASP) boot loader image header may allow an attacker to use attacker-controlled values prior to signature validation potentially resulting in arbitrary code execution.

CVE-2023-20531

Insufficient bound checks in the SMU may allow an attacker to update the SRAM from/to address space to an invalid value potentially resulting in a denial of service.

CVE-2023-20529

Insufficient bound checks in the SMU may allow an attacker to update the from/to address space to an invalid value potentially resulting in a denial of service.

CVE-2023-20530

Insufficient input validation of BIOS mailbox messages in SMU may result in out-of-bounds memory reads potentially resulting in a denial of service.

CVE-2021-26315

When the AMD Platform Security Processor (PSP) boot rom loads, authenticates, and subsequently decrypts an encrypted FW, due to insufficient verification of the integrity of decrypted image, arbitrary code may be executed in the PSP when encrypted firmware images are used.

CVE-2020-12951

Race condition in ASP firmware could allow less privileged x86 code to perform ASP SMM (System Management Mode) operations.

CVE-2021-26331

AMD System Management Unit (SMU) contains a potential issue where a malicious user may be able to manipulate mailbox entries leading to arbitrary code execution.

CVE-2020-12961

A potential vulnerability exists in AMD Platform Security Processor (PSP) that may allow an attacker to zero any privileged register on the System Management Network which may lead to bypassing SPI ROM protections.
